This trailer is detailing the fearsome foes that Sonic must defeat in Sonic Generations. These legendary rivals have appeared in Sonic titles from the Genesis era to the Modern era and are now back to battle Sonic in his new adventure through time.

The Modern Era reveals three new levels inspired by iconic stages from previous modern Sonic titles. The re-imaged zones – Crisis City, Rooftop Run, and Planet wisp – have been redesigned for classic Sonic game play and completely new modern stages to blaze through with Modern Sonic.

It details Sonic's most iconic Genesis era environments featured in the title. Green Hill Zone, Chemical Plant and Sky Sanctuary are all transformed into stunning 3D stages, playable as both modern and classic Sonic.
